Before moving your car from a parked position, you should:

Before moving your car from a parked position, signaling and pulling from the curb when it is safe to do so is crucial for several reasons. Signaling communicates your intention to other road users—this is essential for safety. It ensures that drivers and pedestrians around you are aware that you are about to merge into traffic. This action minimizes the risk of collisions and enhances the overall flow of traffic.

It's also important to wait until it is safe to move out into the roadway; this means checking for oncoming vehicles, cyclists, and pedestrians to ensure that your path is clear. By prioritizing a signal and the safety of the maneuver, you contribute to a more predictable driving environment for everyone on the road.

The other options do not encompass the complete set of actions required to safely move from a parked position. While adjusting your seat and checking mirrors is important for visibility and comfort, it is not sufficient on its own. Looking for pedestrians is certainly vital; however, it does not account for other vehicles or broader situational awareness. Lastly, waiting for a green traffic light is irrelevant since parked vehicles do not typically encounter traffic signals in the same way that moving vehicles do.
